From: Hans de Goede <[email protected]> It is advisable to disable the NMI before registering the IRQ handler as registering the IRQ handler unmasks the IRQ on the GIC, so if U-Boot has left the NMI enabled and the NMI pin is active we will immediately get an interrupt before any driver has claimed the downstream interrupt of the NMI.
